What are the advantages of GIS compared with traditional maps?

Compared with traditional maps, geographic information system has advantages:

(1) It has a large amount of information and is easy to use. Geographic information system can provide various spatial information reflecting the regional situation, and can establish a model to reveal the regional structural characteristics and development laws;

(2) The function is powerful and complete, and the geographic information system can provide many functions such as query and retrieval, spatial analysis, revision and supplement, distance calculation, etc. (3) Be able to carry out dynamic monitoring, evaluation and prediction;

supplement:

1. definition: Geographic Information System (GIS) is sometimes called "Geo－Information system".

it is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the whole or part of the earth's surface space (including the atmosphere) with the support of computer hardware and software systems.

2. Relationship:

Differences and connections between GIS and remote sensing and global positioning system. Remote sensing, global positioning system and GIS both develop independently and promote each other.

Remote sensing is mainly used for obtaining geographic information data, global positioning system is mainly used for spatial positioning of geographic information, and geographic information system is mainly used for managing, querying, updating, spatial analysis and application evaluation of geographic information data.
